RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/800,340 for a “Cup Can,” filed Feb. 1, 2019, and currently co-pending, the entirety of which is incorporated herein by reference.

FIELD OF INVENTION

The present invention relates generally to fluid cans. The present invention relates particularly, though not exclusively, to fluid cans with a cap. The present invention relates more particularly, though not exclusively, to fluid beverage cans with a resealable cap.

BACKGROUND OF THE INVENTION

Cans are utilized to store chemicals, food, beverages, and various other types of contents. Cans used to store chemicals utilize tops with removable tabs of various sizes that can be pulled off or pushed in. Cans used to store food are generally sealed and require a can opener to remove the contents, or may have tops that are entirely removable. Cans used to store beverages utilize tops with tabs of various sizes that can be pulled off or pushed in. Once the tops of the cans are removed they cannot be used to reseal the can; the entire contents must be used or transferred to another container.

Cans used to store fluid with tops using tabs have gone through various iterations that are still used today. Pull-tabs, tabs that are pulled off of the can top, are completely detached from the can and discarded. However, due to the pull-tabs being completely detached from the can they can become swallowing hazards to young children. Stay-on-tabs, tabs that are pushed in by a lever, remains attached to the can top and do not become hazards. However, the single opening of the can has its inherent drawbacks.

The single opening in the can is a fraction of the size of the can top, which is the size of the removed or punched in tab. The single opening provides a single path for fluids to go out of the can and for air to come into the can to replace the removed fluid, which creates a series of pauses in the flow of the fluid as air enters the can to replace the removed fluid. The pauses in fluid flow reduces the overall fluid flow rate of the can. In addition, the pause in fluid flow and the rush of air entering the can agitates the fluid within the can further affecting the fluid flow rate. In order to alleviate the pauses in fluid flow, the size of the opening have been enlarged in certain cans.

The pause in the fluid flow for the air to replace the removed fluid is referred to as the “glug” factor for beverage cans. The “glug” factor and the size of the opening of the can top influences the enjoyment of drinking from the can. The “glug” factor does not provide a smooth drinking experience from a can. For carbonated beverages, the “glug” factor agitates the fluid within the can affecting the fluid flow rate and creates foam, further affecting the drinking experience from a can. To eliminate the “glug” factor, consumers pour the carbonated beverage from a can into a cup. In certain cans, the opening is the size of the can top, but for these types of cans with full-pull out tops the cans are left with sharp edges.

In light of the above, it would be advantageous to provide a resealable top capable of providing a can that is resealable. It would further be advantageous to provide a resealable top capable of providing a smooth drinking surface. It would further be advantageous to provide a resealable top capable of providing a smooth delivery of fluid. It would further be advantageous to provide a resealable top capable of reducing or eliminating the “glug” factor from a beverage can.

As shown, the outer surface 118 is a substantially straight wall extending between the inner edge 104 of the top flange 102 and the bottom of the second wall 116, however it is contemplated that the outer surface 118 may replicate the contours of the first wall 108, the shoulder 110, and the second wall 116 depending on the need and the manufacturing process used.

Referring now to FIG. 9, the top perspective cross-section view of the can lid 100 taken along lines 9-9 of FIG. 7 is shown. The flange 102 has a thickness 101. The first wall 108 has a length 128, the shoulder 110 has a length 129, and the second wall 116 has a length 130. The length 128 of the first wall 108, the length 129 of the shoulder 110, and the length 130 of the second wall 116 add up to equal the length 119 of the outer surface 118.

Referring now to FIG. 10, the cross-section view of the can lid 100 taken along lines 9-9 of FIG. 7 is shown. The can lid 100 includes the top flange 102 with the inner edge 104 and the outer edge 106. Extending vertically downward from the inner edge 104 of the top flange 102 is the first wall 108. Extending horizontally inward from the first wall 108 is the shoulder 110 having the inner edge 112 and the outer edge 114, wherein the first wall 108 is connected to the outer edge 114 of the shoulder 110. Extending vertically downward from the inner edge 112 of the shoulder 110 is the second wall 116. Extending downward, between the inner edge 104 of the top flange 102 and the bottom of the second wall 116, is outer surface 118. The length 103 of the can lid 100 equals the total lengths of the length 128 of the first wall 108, the length 129 of the shoulder 110, the length 130 of the second wall 116, and the flange 102 thickness 101.

The second wall 116 includes the first thread 120, the second thread 122, the third thread 124, and the fourth thread 126. The first thread 120, the second thread 122, the third thread 124, and the fourth thread 126 are substantially similar and thus only the first thread 120 is described. The first thread 120 includes a first segment 120A, which is an elongated body having a first angled face and a second straight face. The first segment 120A is joined to second segment 120B, which is an elongated body with a first straight face and a second straight face.

The bottom wall 170 has a height 171. The height 152, height 161, and height 171 in total is the height 151 of the cap 150. The handle 180 has a height 184. The cavity 172 has a height 173. The tabs, 190, 192, 194, and 196, has a height 191.

Referring now to FIG. 18, a top perspective cross-section view of the resealable top 10 taken along line 18-18 of FIG. 1 is shown. The cap 150 is secured to the can lid 100. In the preferred embodiment, the cap 150 is secured to the can lid 100 by placing the cap 150 on the can lid 100 and rotating the cap 150 until the first tab 190, the second tab 192, the third tab 194, and the fourth tab 196 (collectively referred to as “tabs”) contacts the first thread 120, the second thread 122, the third thread 124, and the fourth thread 126 (collectively referred to as “threads”). The pairing of a tab with a thread is inconsequential as the tabs and the threads are equally spaced apart to allow any tab to engage with any thread. Once the tabs are in contact with the threads, the cap 150 is rotated to engage the tabs with the threads of the can lid 100 until the cap 150 is locked onto the can lid 100. Due to the configuration of the threads, the cap 150 is simultaneously pulled downward when the cap 150 is rotated.

As the cap 150 is rotated, the tabs slide along the threads of the can lid 100 and pulls the cap 150 downward. Since each of the tabs and each of the threads are substantially similar, for purposes of illustrating the engagement of the tabs and the threads, tab 190 and thread 120 will be described, in conjunction with FIG. 10. As the cap 150 is rotated, tab 190 slides along thread 120. Tab 190 is chamfered and allows for smooth movement of the tab 190 along the thread 120. Tab 190 is initially in contact with the first segment 120A, which has an angled face. The angled face of the first segment 120A provides for easier engagement with the tab 190. Once passed the first segment 120A, the tab 190 slides along the second segment 120B until the tab 190 contacts the third segment 120C. The third segment 120C is angled downward and connects the second segment 120B with the fourth segment 120D. The tab 190 slides along the third segment 120C and transitions the tab 190 from the second segment 120B to the fourth segment 120D, which is located at a lower height. The change in height of the second segment 120B and the fourth segment 120D of the can lid 100 pulls the cap 150 downwards while sliding along the third segment 120C. The tab 190 further slides along the fourth segment 120D until the tab is stopped by the fifth segment 120E and the cap 150 can no longer rotate. The cap 150 is locked into place on the can lid 100 when the cap 150 can no longer rotate.

To remove the cap 150 from the can lid 100, the cap 150 is rotated in the opposite direction. Once the cap 150 is removed from the can lid 100, a large opening the size of diameter 117 is provided. All of the edges of the can lid 100 are smooth, such as the threads, the top flange 152, the first wall 108, and shoulder 110, ensuring that there are no sharp edges that may cut a user.

Referring now to FIG. 19, a cross-section view of the resealable top 10 taken along line 18-18 of FIG. 1 is shown. The diameter 174 of the bottom wall 170 of the cap 150 is smaller than the diameter 117 of the second wall 116 of the can lid 100. The diameter 157 of the top flange 152 of the cap 150 is larger than the diameter of the shoulder 110 and the diameter 117 of the second wall 116 of the can lid 100. This allows the cap 150 to be inserted into the can lid 100 without going completely through the can lid 100.

As the cap 150 is pulled downwards, the top flange 152 of the cap 150 comes into contact with the first wall 108 of the can lid 100 and the curved portion 169 of the first wall 160 of the cap 150 comes into contact with the shoulder 110 of the can lid 100 sealing the opening of the can lid 100. The diameter 157 of the top flange 152 is approximately equal to the diameter 113 of the first wall 118, which the first wall 118 is slighted tapered inward with a slight decrease in diameter at the junction of the first wall 118 and the shoulder 110 to facilitate a seal between the top flange 152 and the first wall 108. It is contemplated that a gasket may be placed between the can lid 100 and the cap 150 to provide an alternative means of sealing the can lid 100 opening. The gasket may be placed on the can lid 100 on the shoulder 110 or the first wall 108. Alternatively, the gasket may be placed on the cap 150 at the curved portion 169 of the outer surface 168 of the first wall 160 or on the top flange 152.

When secured, the resealable top 10 provides a top surface substantially similar to the top surface of standard beverage cans. The cap 150 is secured onto the can lid 100 below the height of the top flange 102 of the can lid 100. The can lid 100 has a height of 103 and the cap has a height of 151. When the cap 150 is secured onto the can lid 100, the bottom wall 170 of the cap 150 is parallel with the bottom of the second wall 116 of the can lid 100, leaving a height 140 of the can lid 100 exposed. The exposed height 140 of the can lid 100 provides a top surface that is substantially similar to the top surfaces of standard cans. The top surface of the resealable top 10 facilitates the stacking of cans utilizing the resealable top 10 as well as standard beverage cans. In a preferred embodiment of the invention, the resealable top 10 is utilized as a top for a carbonated beverage can. Due to the large opening of the resealable top 10, the “glug” factor is eliminated. The can lid 100 provides smooth surfaces eliminating the possibility of a person cutting their lips from drinking directly from the resealable top 10. Further, the cap 150 may be used to close the opening of the can lid 100 preserving the carbonation of the beverage for consumption at a later time.

The pairing of a tab with a thread is inconsequential as the tabs and the threads are equally spaced apart to allow any tab to engage with any thread. Once the tabs are in contact with the threads, the cap 200 is rotated to engage the tabs with the threads of the can lid 100 until the cap 200 is locked onto the can lid 100. Due to the configuration of the threads, the cap 200 is simultaneously pulled downward when the cap 200 is rotated. As the cap 200 is rotated, the tabs slide along the threads of the can lid 100 and pulls the cap 200 downward. The diameter 215 of the outer wall 220 of the cap 200 is smaller than the diameter 117 of the second wall 116 of the can lid. The outer edge 206 of the top flange 202 has a diameter 207, which is larger than the diameter 113 of the shoulder 110 and the diameter 117 of the second wall 116 of the can lid 100. This allows the cap 200 to be inserted into the can lid 100 without going completely through the can lid 100.

The tabs of the cap 200 are configured substantially similar to the tabs of the cap 150. The method of securing the cap 200 to the can lid 100 is substantially similar to the method of securing the cap 150 to the can lid 100, and thus will not be further described herein. To remove the cap 200 from the can lid 100, the cap 200 is rotated in the opposite direction. Once the cap 200 is removed from the can lid 100, a large opening is provided. All of the edges of the can lid 100 are smooth, ensuring that there are no sharp edges that may cut a user.

As the cap 200 is pulled downwards, the top flange 202 of the cap 200 comes into contact with the first wall 108 and the shoulder 110 of the can lid 100 sealing the opening of the can lid 100. It is contemplated that a gasket may be placed between the can lid 100 and the cap 200 to provide an alternative means of sealing the can lid 100 opening. The cap 200 is secured onto the can lid 100 below the height of the top flange 102 of the can lid 100. When secured, the resealable top 20 provides a top surface substantially similar to the top surface of standard beverage cans. The top surface of the resealable top 20 facilitates the stacking of cans utilizing the resealable top 20 as well as standard beverage cans.
